“…These values are close to the sum of the effective ionic radii of 1.37 Å and the expected angle of 120°. The B–N distances of 1.29–1.31 Å are also in the range reported for linear BN 2 units. − A detailed list of interatomic distances and angles is given in Table .…”

The host structure of the new phosphor Sr 6 (BO 3 ) 3 BN 2 :Eu 2+ crystallizes tetragonally (Sr 6 (BO 3 ) 3 BN 2 , P4 2 / mbc, Z = 8, a = 12.8173(3) Å, b = 14.0740(5) Å, R int = 0.037, R 1 = 0.052, and wR 2 = 0.121) and features the two borate anions BN 2 3− localized within a channel formed by Sr 2+ and BO 3 3− in the same material. Furthermore, spectroscopic data (infrared, Raman, and UV−vis) are discussed, and the first results on the luminescence properties of Sr 6 (BO 3 ) 3 BN 2 :Eu 2+ with an emission−emission peaking at 618 nm upon excitation peaking at 465 nm are presented. Electronic structure calculations yield a band gap of 3.91 eVwith the nitrogen atoms being responsible for the smaller band gap than oxoboratesand confirm the disorder of the BN 2 3− ions.

“…CN 2 2– ), only 2‐D and 3‐D N A e 6 frameworks have been known so far. While the anions diazenide N 2 2– (Sr 4 N 3 ), boronitride BN 2 3– (Ca 3 N[BN 2 ]), or halide (Ca 2 N X with X = F, Cl, Br, I) are found exclusively in layered structures, 2‐D structures (e.g. in Ba 5 [CN 2 ]N 2 ) and 3‐D frameworks (e.g.…”

“…The first experimental realization of the fully deprotonated acetonitrile anion CCN 3– in the nitridometalate host of Ba 5 [TaN 4 ][C 2 N], raised the question, whether this CO 2 ‐isoelectronic anion could be stabilized in a pure cationic environment as well. Since similar molecular anions, such as CN 2 2– carbodiimide or BN 2 3– boronitride form various crystal structures as alkaline earth salts, ternary acetonitriletriide salts were explored. Most known ternary Sr–C–N compounds contain only one carbon species, e.g.…”

Sr₄N[CN₂][C₂N]: The First Carbodiimide Acetonitriletriide

et al. 2019

The acetonitriletriide anion C 2 N 3-, the fully deprotonated form of acetonitrile, is stabilized in a pure alkaline earth metal environment in Sr 4 N[CN 2 ][C 2 N]. The heterogeneous reaction of graphite and elemental nitrogen (from decomposed NaN 3 ) with Sr 2 N at 1020 K yields for the first time a phase that contains the two triatomic anions acetonitriletriide C 2 N 3and carbodiimide CN 2 2side by side. Further synthetic routes were likewise successfully tested, including a sodium free approach [a]

“…An incorporation of Eu 2+ ions into the Mg 3 (BN 2 )N structure was also explored in attempt to expand the lattice with larger ions such as Ca 2+ , Sr 2+ or Ba 2+ . Pure Ca 3 (BN 2 )N was not included into this study because it decomposes in moist air 16…”

“…More examples of di‐nitridoborates were discovered, including a substantial number of mixed alkali/alkaline earth compounds such as A ( AE )(BN 2 ) or A( AE ) 4 (BN 2 ) 3 7. In addition, there are examples of mixed anion compounds having formulas such as Ba 4 (BN 2 ) 4 O8 or AE 3 (BN 2 )N ( AE = Mg, Ca) 9,10. A common feature of all these compounds is that, unfortunately, they behave sensitive against moist air, due to the formation of ammonia.…”
